Confirmed line-ups: Olympiacos vs Arsenal: Martinelli & Willock start

Arsenal take on Olympiacos at the Karaiskakis Stadium this evening in the first leg of our Europa League last-32 tie.

Mikel Arteta has decided to stick with number one goalkeeper Bernd Leno for the game with Emi Martinez having to settle for a place on the bench despite featuring throughout the group stages.

It appears Shkodran Mustafi or Sokratis will start at right-back with Bukayo Saka and David Luiz making-up the back four. Matteo Guendouzi is recalled to start alongside Granit Xhaka in midfield while Joe Willock replacing Mesut Ozil.

Alexandre Lacazette is recalled up front with Gabriel Martinelli and Pierre-Emerick Aubameyang offering support so Nicolas Pepe has to settle for a place on the bench.
